Service Relationships Identification

The Global Service Relationship Number (GSRN) is the GS1 Identification Key used to identify the recipient of services in the context of a service relationship (eg. membership in a frequent flyer or loyalty program). It is used to enable access to a database entry for recording recurring services. The GSRN is usually assigned by the service provider.

The GSRN is constructed as:
